Description

Technical Field

[0001] This utility model relates to the field of cement production line technology, and more specifically, it relates to a cement feeding device for a cement production line. Background Technology

[0002] In the material conveying process of a cement production line, accurately controlling the cement feeding height is crucial to ensuring production efficiency and product quality. This requires the feeding device to have the ability to flexibly adjust the height to adapt to storage silos and conveying equipment of different specifications.

[0003] However, existing height adjustment mechanisms generally use bolt fixing or hydraulic locking methods. Operators need to use special tools for cumbersome adjustment operations. Each adjustment requires first loosening the fixing device, then manually adjusting the height position, and finally re-locking the fixing parts. This not only consumes a lot of time, but also causes the fixing parts to wear out due to frequent disassembly and assembly, reducing the service life of the equipment. It also increases the labor intensity and safety risks for workers. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a cement feeding device for a cement production line to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cement feeding device for a cement production line, comprising a base, a conveying mechanism on the base, and an adjusting mechanism below the conveying mechanism. The adjusting mechanism includes a support frame, support rods, adjusting holes, a mounting frame, a hydraulic cylinder, and a fixing mechanism. The support frame is fixed on the base, and multiple sets of sliding members are provided within the support frame. Multiple sets of adjusting holes are distributed on the outer walls of multiple sets of support rods. The mounting frame rotates within the support frame, and the hydraulic cylinder is fixed to the outer wall of the mounting frame. The fixing mechanism includes an insert rod, a fixing sleeve, a slider, a locking block, a pushing block, a slot, and a limiting mechanism. The insert rod is inserted into the support frame and the adjusting hole. The fixing sleeve is inserted into the top of the insert rod. Multiple sets of sliders are provided on the outer wall of the fixing sleeve. The locking block is fixed to the bottom of multiple sets of sliders. The pushing block is fixed to the top of multiple sets of sliders. The slot is provided on the outer wall of the insert rod.

[0008] The present invention is further configured such that the limiting mechanism includes a limiting sleeve, a transmission sleeve, a limiting plate, a screw, a gear, a rotating sleeve, and a gear ring. The limiting sleeve slides on the outer wall of the fixed sleeve, the transmission sleeve is fixed on the outer wall of the limiting sleeve, the limiting plate is fixed on the outer wall of the fixed sleeve, the screw is provided with multiple sets rotating on the outer wall of the fixed sleeve and all threadedly connected to the transmission sleeve, the gear is provided with multiple sets fixed on the top of the screw and rotatably connected to the limiting plate, the rotating sleeve rotates on the outer wall of the fixed sleeve, and the gear ring is fixed on the bottom surface of the rotating sleeve and meshes with multiple sets of gears. This structure forms a precise gear transmission system, and the entire limiting mechanism can be driven to work by the simple rotation of the rotating sleeve, which greatly simplifies the operation process and improves the locking accuracy and work efficiency.

[0009] The present invention is further configured such that the inner wall of the fixed sleeve is provided with a positioning strip and the outer wall of the insertion rod is provided with a positioning groove. The positioning strip and the positioning groove are provided in multiple sets and are slidably connected. This design ensures that the insertion rod can only move axially within the fixed sleeve and will not rotate. The multiple sets of cooperation enhance the anti-torsion ability and improve the stability and positioning accuracy of the locking system.

[0010] The present invention is further configured such that the outer wall of the fixed sleeve is provided with a movable groove, and the movable groove is provided with multiple sets distributed on the outer wall of the fixed sleeve and slidably connected to multiple sets of push blocks respectively. This multi-channel sliding structure enables the push blocks to move smoothly in the movable groove, ensuring uniform distribution of force transmission, while providing a reliable guiding effect, enhancing the overall strength and operational stability of the locking mechanism.

[0011] The present invention is further configured such that push springs are connected between the inner walls of the multiple sets of push blocks and the movable grooves, and multiple sets of push springs are provided. This elastic reset mechanism provides a continuous and stable restoring force for the push blocks, ensuring that the push blocks can automatically return to their original positions after the limit sleeve is released, thereby realizing the quick unlocking function and reducing the difficulty of operation and time cost.

[0012] The present invention is further configured such that the outer walls of the multiple sets of push blocks are all set as inclined surfaces, and the two ends of the limiting sleeve are all provided with rounded corners. This wedge-shaped contact design enables the limiting sleeve to smoothly push the push block along the inclined surface during the sliding process, reducing motion impact and frictional resistance, reducing component wear rate, and extending the service life of the mechanism.

[0013] The present invention is further configured such that the conveying mechanism includes a feeding pipe, a motor, a rotating rod, a spiral plate, a discharge pipe, and an inlet hopper. The feeding pipe rotates at one end of the base, the motor is fixed at one end of the feeding pipe, the rotating rod rotates inside the feeding pipe and is fixedly connected to the output end of the motor, the spiral plate is fixed to the outer wall of the rotating rod, the discharge pipe is fixed to the outer wall of the top end of the feeding pipe, and the inlet hopper is fixed to the outer wall of the bottom end of the feeding tank. This integrated conveying system achieves continuous and stable material conveying through the spiral conveying principle, meeting the high efficiency and stability requirements of cement production for material conveying. At the same time, the structure is compact and easy to adjust the overall height.

[0014] The present invention is further configured such that the outer wall of the feeding tube is rotatably connected to multiple sets of support rods, the telescopic end of the hydraulic cylinder is rotatably connected to the outer wall of the feeding tube, a sliding hole is provided in the insert rod, a compression spring is connected in the sliding hole, and a top block is connected to the top of the compression spring and slidably connected to the sliding hole. This automatic ejection mechanism allows the insert rod to push the top block to automatically disengage with the help of the spring force when it is unlocked. At the same time, the rotatable connection between the hydraulic cylinder and the support rod ensures that the feeding tube can be adjusted smoothly and accurately, thereby improving the automation level and ease of operation of the equipment.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a cement feeding device for a cement production line, which has the following beneficial effects:

[0017] 1. The adjustment mechanism consists of a support frame, support rods, adjustment holes, mounting bracket, and hydraulic cylinder. It effectively solves the problem of cumbersome cement conveying height adjustment mentioned in the background technology. This mechanism adopts a design in which multiple sets of support rods slide within the support frame, and with multiple sets of distributed adjustment holes, it provides multi-level precise positioning options for height adjustment. The mounting bracket is rotatably connected within the support frame and works in conjunction with the hydraulic cylinder to form a power drive system. The hydraulic cylinder is fixed to the outer wall of the mounting bracket, and its telescopic movement can precisely control the rotation angle and height position of the feeding pipe. This innovative structure allows production line workers to quickly adjust the feeding height in harsh environments with high dust without frequently using special tools, greatly improving operating efficiency and production continuity. It is particularly suitable for cement production environments that require frequent adjustments.

[0018] 2. The fixing mechanism includes an insert rod, a fixing sleeve, a slider, a locking block, a push block, a locking groove, and a limiting mechanism. It cleverly solves the problem of cumbersome support fixing and unlocking operations mentioned in the background technology. This mechanism utilizes the locking principle of the locking block and the locking groove, combined with the push block design guided by the movable groove, to achieve rapid locking and releasing of the adjusted position. The limiting mechanism, through the precise cooperation of the limiting sleeve, transmission sleeve, limiting plate, screw, gear, rotating sleeve, and gear ring, constructs a composite power system of gear transmission and threaded feed. The push spring provides reset power for the push block, ensuring that the locking block can quickly disengage during unlocking. The cooperation between the positioning strip and the positioning groove prevents the insert rod from rotating, ensuring locking accuracy and stability. These designs significantly simplify the locking and unlocking operation process, allowing operators to achieve secure locking through simple rotation without additional tools. This effectively solves the problem of loosening of the support structure in high-vibration environments, improving the service life and safety of the equipment.

[0019] 3. The conveying mechanism consists of a feeding pipe, motor, rotating rod, spiral plate, discharge pipe, and inlet hopper. It innovatively solves the balance problem between feed height adjustment and conveying efficiency mentioned in the background technology. This mechanism uses a motor-driven rotating rod to rotate the spiral plate, achieving continuous and stable conveying of cement materials. The feeding pipe is rotatably connected to the support rod, and its rotation angle is controlled by a hydraulic cylinder, allowing the conveying system to adjust the feed height while maintaining operation. The design of the inlet hopper and discharge pipe ensures smooth material entry and exit, reducing the risk of blockage. The coordinated operation of the entire conveying system and the adjustment mechanism enables the production line to quickly adjust parameters according to the production needs of different batches, achieving height changes without interrupting production. This significantly improves production flexibility, reduces adjustment time and material waste, and provides a more efficient and environmentally friendly feeding solution for cement production.

[0029] Please see Figures 1-5 A cement feeding device for a cement production line includes a base 1, a conveying mechanism on the base 1, and an adjusting mechanism below the conveying mechanism. The adjusting mechanism includes a support frame 2, a support rod 3, an adjusting hole 4, a mounting frame 5, a hydraulic cylinder 6, and a fixing mechanism. The support frame 2 is fixed on the base 1 and has multiple sets of sliding parts within it. The adjusting hole 4 has multiple sets distributed on the outer walls of the multiple sets of support rods 3. The mounting frame 5 rotates within the support frame 2, and the hydraulic cylinder 6 is fixed to the outer wall of the mounting frame 5. The fixing mechanism includes an insertion rod 7, a fixing sleeve 8, a slider 9, a locking block 10, a pushing block 11, a slot 12, and a limiting mechanism. The insertion rod 7 is inserted into the support frame 2 and the adjusting hole 4. The fixing sleeve 8 is inserted into the top of the insertion rod 7. The slider 9 has multiple sets of sliding parts on the outer wall of the fixing sleeve 8. The locking block 10 is fixed to the bottom of the multiple sets of sliders 9, the pushing block 11 is fixed to the top of the multiple sets of sliders 9, and the slot 12 is located on the outer wall of the insertion rod 7.

[0030] The limiting mechanism includes a limiting sleeve 13, a transmission sleeve 14, a limiting plate 15, a screw 16, a gear 17, a rotating sleeve 18, and a gear ring 19. The limiting sleeve 13 slides on the outer wall of the fixed sleeve 8, the transmission sleeve 14 is fixed on the outer wall of the limiting sleeve 13, the limiting plate 15 is fixed on the outer wall of the fixed sleeve 8, the screw 16 is provided with multiple sets rotating on the outer wall of the fixed sleeve 8 and all are threadedly connected to the transmission sleeve 14, the gear 17 is provided with multiple sets fixed on the top of the screw 16 and all are rotatably connected to the limiting plate 15, the rotating sleeve 18 rotates on the outer wall of the fixed sleeve 8, and the gear ring 19 is fixed on the bottom surface of the rotating sleeve 18 and meshes with multiple sets of gears 17. The rotational motion of the rotating sleeve 18 is transmitted to the gears 17 through the gear ring 19, the gears 17 drive the screw 16 to rotate, and the rotational motion is converted into the axial movement of the limiting sleeve 13 by the transmission sleeve 14 through the threaded pair, forming a complete mechanical transmission chain.

[0031] The inner wall of the fixed sleeve 8 is provided with a positioning strip 20, and the outer wall of the insertion rod 7 is provided with a positioning groove 21. Multiple sets of positioning strips 20 and positioning grooves 21 are provided and slidably connected. Through the sliding cooperation of multiple sets of positioning strips 20 and positioning grooves 21, the insertion rod 7 is restricted to axial movement within the fixed sleeve 8 and cannot rotate, thus ensuring the positioning accuracy and movement stability of the locking system.

[0032] The outer wall of the fixed sleeve 8 is provided with a movable groove 22. The movable groove 22 is provided with multiple sets distributed on the outer wall of the fixed sleeve 8 and slidably connected to multiple sets of push blocks 11 respectively. The movable groove 22 serves as the movement track of the push blocks 11, restricting the push blocks 11 to move only in the radial direction, thus ensuring the movement accuracy and positioning accuracy of the push blocks 11 on the surface of the fixed sleeve 8.

[0033] Push springs 23 are connected between the inner walls of multiple push blocks 11 and the movable groove 22. There are multiple sets of push springs 23. The push springs 23 store energy when under pressure. When the limiting sleeve 13 releases the restriction on the push block 11, the push springs 23 release energy to push the push block 11 back to its original position, realizing the automatic reset function.

[0034] The outer walls of multiple push blocks 11 are all set as inclined surfaces, and the ends of the limiting sleeve 13 are all provided with rounded corners. The rounded corners of the limiting sleeve 13 and the inclined surfaces of the push blocks 11 form a sliding contact surface, so that the axially moving limiting sleeve 13 can smoothly convert the axial force into the radial force that pushes the push blocks 11, reducing impact and wear.

[0035] The conveying mechanism includes a feeding pipe 24, a motor 25, a rotating rod 26, a spiral plate 27, a discharge pipe 28, and an inlet hopper 29. The feeding pipe 24 rotates at one end of the base 1, the motor 25 is fixed at one end of the feeding pipe 24, the rotating rod 26 rotates inside the feeding pipe 24 and is fixedly connected to the output end of the motor 25, the spiral plate 27 is fixed to the outer wall of the rotating rod 26, the discharge pipe 28 is fixed to the outer wall of the top end of the feeding pipe 24, and the inlet hopper 29 is fixed to the outer wall of the bottom end of the feeding tank. The motor 25 provides power to drive the rotating rod 26 to rotate, and the rotating rod 26 drives the spiral plate 27 to rotate to form a continuous spiral thrust, so that the cement material is continuously conveyed along the inside of the feeding pipe 24 from the inlet hopper 29 to the discharge pipe 28.

[0036] The outer wall of the feeding pipe 24 is rotatably connected to multiple sets of support rods 3. The telescopic end of the hydraulic cylinder 6 is rotatably connected to the outer wall of the feeding pipe 24. A sliding hole 30 is opened in the insertion rod 7. A compression spring 31 is connected in the sliding hole 30. A top block 32 is connected to the top of the compression spring 31 and is slidably connected to the sliding hole 30. The hydraulic cylinder 6 controls the rotation angle of the feeding pipe 24 to achieve height adjustment. At the same time, the compression spring 31 and the top block 32 in the insertion rod 7 form an automatic pop-out mechanism. In the unlocked state, the insertion rod 7 can be automatically pushed out of the fixing sleeve 8 and the adjustment hole 4, simplifying the unlocking operation.

[0037] In this embodiment, cement is injected into the feeding pipe 24 through the inlet hopper 29. The motor 25 drives the rotating rod 26 to rotate, which in turn drives the spiral plate 27 to rotate and transport the cement. The cement is then transported to subsequent equipment through the discharge pipe. When it is necessary to adjust the inlet height of the feeding pipe 24, the hydraulic cylinder 6 is activated so that its telescopic end pushes the feeding pipe 24 to rotate along the base 1. The feeding pipe 24 drives the support rod 3 to slide along the support frame 2. After adjusting to a suitable height, the adjusting hole 4 is aligned with the fixing sleeve 8, and then the insertion rod 7 is inserted into the adjusting hole 4 and the fixing sleeve 8. Inside, the top block abuts against the inner wall of the fixed sleeve 8 and squeezes the compression spring. Then, the rotating sleeve 18 rotates clockwise to drive the gear ring 19 to mesh with multiple sets of gears 17, so that the multiple sets of gears 17 drive the screw 16 to rotate and engage with the transmission sleeve 14. This causes the transmission sleeve 14 to drive the limiting sleeve 13 to abut against the outer wall of multiple sets of push blocks 11, pushing the multiple sets of push blocks 11 to slide along the movable groove 22 to squeeze the push spring 23. Through multiple sets of sliders 9, the locking block 10 is pushed to engage in the locking groove 12 to lock the insertion rod 7. This process is repeated to fix multiple sets of support rods 3.

[0038] More specifically, when it is necessary to unlock multiple sets of support rods 3, the counterclockwise rotation of the rotating sleeve 18 drives multiple sets of gears 17 to rotate through the gear ring 19, and drives multiple sets of screws 16 to engage with the transmission sleeve 14, so that the transmission sleeve 14 drives the limiting sleeve 13 to release the contact with multiple sets of push blocks 11. Multiple sets of push springs 23 push the push blocks 11 to slide along the movable groove 22, and the slider 9 pulls the locking block 10 to disengage from the locking groove 12 to release the locking of the insertion rod 7. Then, the pressure spring resets and pushes the top block, and the top block pushes the insertion rod 7 to disengage from the fixing sleeve 8 and the adjusting hole 4, thereby releasing the fixation of the support rod 3.

[0039] In summary, during the use or operation of the overall equipment: cement is injected into the feeding pipe 24 through the inlet hopper 29. The motor 25 drives the rotating rod 26 to rotate, which in turn drives the spiral plate 27 to rotate and transport the cement. Subsequently, the cement is transported to the downstream equipment through the discharge pipe. When it is necessary to adjust the inlet height of the feeding pipe 24, the hydraulic cylinder 6 is activated, causing its telescopic end to push the feeding pipe 24 to rotate along the base 1. The feeding pipe 24 drives the support rod 3 to slide along the support frame 2. After adjusting to the appropriate height, the adjusting hole 4 is aligned with the fixing sleeve 8, and then the insertion rod 7 is inserted into the adjusting hole 4 and... Inside the fixed sleeve 8, the top block abuts against the inner wall of the fixed sleeve 8 and squeezes the compression spring. Then, the rotating sleeve 18 rotates clockwise to drive the gear ring 19 to mesh with multiple sets of gears 17, so that the multiple sets of gears 17 drive the screw 16 to rotate and engage with the transmission sleeve 14. This causes the transmission sleeve 14 to drive the limiting sleeve 13 to abut against the outer wall of multiple sets of push blocks 11, pushing the multiple sets of push blocks 11 to slide along the movable groove 22 to squeeze the push spring 23. Through multiple sets of sliders 9, the locking block 10 is pushed to engage in the locking groove 12 to lock the insertion rod 7. This process is repeated to fix multiple sets of support rods 3.

[0040] When it is necessary to unlock multiple sets of support rods 3, the counterclockwise rotation of the rotating sleeve 18 drives multiple sets of gears 17 to rotate through the gear ring 19, and drives multiple sets of screws 16 to engage with the transmission sleeve 14. This causes the transmission sleeve 14 to drive the limiting sleeve 13 to release the contact with multiple sets of push blocks 11. Multiple sets of push springs 23 push the push blocks 11 to slide along the movable groove 22, and the slider 9 pulls the locking block 10 to disengage from the locking groove 12 to release the locking of the insertion rod 7. Then, the pressure spring resets and pushes the top block, and the top block pushes the insertion rod 7 to disengage from the fixing sleeve 8 and the adjusting hole 4, thereby releasing the fixation of the support rod 3.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
